Toilet overflow prevention system

ABSTRACT

A toilet overflow prevention system is provided and is incorporated with an otherwise standard toilet wherein the toilet bowl thereof is incorporated with an overflow inlet portal defined as a generally circular opening integrally formed within the left side of the concave inner wall of the toilet bowl. The overflow inlet portal provides passage to an auxiliary waste drain outlet which extends downward through toilet bowl frontal to the primary waste discharge pipe, and through the stool portion of the standard toilet, under which connection is made to an auxiliary waste outlet piping being in fluid communication with the primary waste discharge pipe. A reticulated grate element is mounted transversely atop the circular opening in order to trap debris contained within toilet bowl so as to facilitate ascension and discharge of water through auxiliary waste drain outlet, hence preventing unpleasant overflow.

RELATED APPLICATIONS

The present invention was first described in Disclosure Document Registration 523,235 filed on Dec. 16, 2002 under 35 U.S.C. §122 and 37 C.F.R. §1.14. There are no previously filed, nor currently any co-pending applications, anywhere in the world.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to toilet flushing systems and, more particularly, to a toilet overflow prevention system.

2. Description of the Related Art

Most everyone has at one time or another dealt with the common occurrence of a clogged toilet. Toilet bowls may become clogged due to any number of reasons. Most often, the waste line becomes obstructed because of excessive waste matter, toilet tissue, or the flushing of inappropriate articles. The undesired result is typically toilet overflow which can lead to substantial property damage and unsanitary conditions.

Accordingly, a need has arisen for a means by which excessive toilet overflow can be effectively discharged through an auxiliary passage so as to prevent an overflow from occurring in a manner which is quick, easy, and efficient. The development of the toilet overflow prevention system fulfills this need.

A search of the prior art did not disclose any patents that read directly on the claims of the instant invention; however, the following references were considered related.

DESCRIPTION OF THE PREFERRED EMBODIMENT

1. Detailed Description of the Figures

Referring now to FIGS. 1-5 a toilet overflow prevention system 10 is shown, according to the present invention, comprised of an otherwise standard toilet 20 which includes a stool 22, a toilet bowl 24, a toilet bowl rim 26 with tank 28 mounted thereon, and flush conduits 29 located inside toilet bowl 24 just below toilet bowl rim 26. Contents of toilet bowl 24 is expelled via standard flushing mechanism 27 through a primary waste discharge pipe 25. Standard flushing mechanism 30 includes a flapper valve 32 being pivotally movable between open and closed positions, whereupon in a closed position, flapper valve 32 effectively blocks water flow from tank 28. An end of a chain 34 is connected to flapper valve 32, wherein chain 34 has a lever 36 mounted at an opposed end thereof and a handle 38 is rotatably attached to lever 36 via pin 37. Downward force applied to handle 38 facilitates an upward pull of chain 34 by lever 36, in turn actuating flapper valve 32 to an open position, thereby allowing water within tank 28 to flow to toilet bowl 24 via outlet port 39 to flush contents thereof through the primary waste discharge pipe 25.

Referring more specifically to FIGS. 1, and 3-5, in order to prevent the toilet bowl 24 from overflowing and flooding the lavatory area resulting in significant property damage as well as producing an unsanitary condition, an overflow inlet portal 40 is provided. The overflow inlet portal 40 is defined as a generally circular opening 41 integrally formed within the left side of the concave inner wall of the toilet bowl 24, at a level below the flush conduits 29, which provides passage to an auxiliary waste drain outlet 44. The circular opening 41 has a diameter measuring approximately 1.5 inches and is smoothly textured and contoured so as to facilitate swirling action of water upon contact therewith. Placement of overflow inlet portal 40 below the flush conduits 29 allows water to flow into auxiliary waste drain outlet 44 with each flush, thereby maintaining fresh water therein so as to prevent objectionable sewer gases from dissipating throughout the home.

The auxiliary waste drain outlet 44 extends downward through toilet bowl 24 frontal to primary waste discharge pipe 25, and through stool 22 under which connection is made to an auxiliary waste outlet piping 46 which is in fluid communication with primary waste discharge pipe 25. Connection between auxiliary waste drain outlet 44 and auxiliary waste outlet piping 46 is effectuated utilizing rubber gaskets 44 a, fittings, and additional requisite components of proper configuration being adapted to prevent leakage between drain outlet 44 and outlet piping 46, as well as between outlet piping 46 and primary waste discharge pipe 25.

In order to trap debris contained within toilet bowl 24 so as to facilitate ascension and discharge of water through auxiliary waste drain outlet 44 and hence prevent unpleasant overflow, a reticulated grate element 60 is provided. The reticulated grate element 60 is mounted transversely atop the circular opening 41.
